SPODUMENE CRUSHER-lithium
Lithium is a soft, silver-white metal that belongs to the alkali metal group of chemical elements. It is represented by the symbol Li, and it has the atomic number 3. Under standard conditions it is the lightest metal and the least dense solid element. Like all alkali metals.
Lithium Application:
Because of its specific heat capacity, lithium is often used in coolants for heat transfer applications.
Lithium
is used in lithium-ion batteries because of its high electrochemical potential, a typical cell can generate approximately 3 volts, compared with 2.1 volts for lead/acid or 1.5 volts for zinc-carbon cells.
Lithium is also used in the pharmaceutical and fine-chemical industry in the manufacture of organolithium reagents, which are used both as strong bases and as reagents for the formation of carbon-carbon bonds.
Lithium mining
Native lithium is rare in nature. Most of the lithium is extracted from the mining spodumene. The extraction of lithium is a very complex process, in which many machines and equipment will be used. Zenith can supply crusher and grinding mill for crushing process and grinding process.
Spodumene Crusher and Spodumene Grinding Mill
The common spodumene crushing and grindng process is below. The raw spodumene is feeded to jaw crusher and crushed in jaw crusher down to 5 mm particle size, then crushed spodumene is feeded into the ball mill for grinding. The final product of crushing and grinding process will be processed and extracted by other equipment. Zenith can supply jaw crusher as spodumene primary crusher and cone crusher as secondary crusher if necessary. Additional, Zenith can provide ball mill for grinding spodumene. Zenith coarse powder mill and MTM trapezium mill is a good substitute of ball mill.
Lithium fluoride, artificially grown as crystal, is clear and transparent and often used in specialist optics for IR, UV and VUV (vacuum UV) applications. It has one of the lowest refractive indexes and the farthest transmission range in the deep UV of most common materials. Finely divided lithium fluoride powder has been used for thermoluminescent radiation dosimetry (TLD): when a sample of such is exposed to radiation, it accumulates crystal defects which, when heated, resolve via a release of bluish light whose intensity is proportional to the absorbed dose, thus allowing this to be quantified. Lithium fluoride is sometimes used in focal lenses of telescopes. The high non-linearity of lithium niobate also makes it useful in non-linear optics applications.
The launch of a torpedo using lithium as fuel
Metallic lithium and its complex hydrides, such a Li[AlH4], are used as high energy additives to rocket propellants. Lithium peroxide, lithium nitrate, lithium chlorate and lithium perchlorate are used as oxidizers in rocket propellants, and also in oxygen candles that supply submarines and space capsules with oxygen. The Mark 50 Torpedo Stored Chemical Energy Propulsion System (SCEPS) uses a small tank of sulfur hexafluoride gas which is sprayed over a block of solid lithium. The reaction generates enormous heat which is used to generate steam from seawater. The steam propels the torpedo in a closed Rankine cycle.
Lithium hydroxide and lithium peroxide are used in confined areas, such as aboard spacecraft and submarines, for air purification. Lithium hydroxide absorbs carbon dioxide from the air by reacting with it to form lithium carbonate, and is preferred over other alkaline hydroxides for its low weight. Lithium peroxide (Li2O2) in presence of moisture not only absorbs carbon dioxide to form lithium carbonate, but also releases oxygen.
